sanction could be obtained for practically testing the area by borings, the
previous conceptions as to the poverty and worthlessness of the coal
might possibly have to be modified.

So long as the Umaria coal was supposed to be of upper-Géndwéna
age, and that was the opinion entertained of it up to the time of our
examination,! it would have been running counter to our experience to
have recommended a special scheme of exploration ; but so soon as the coal
was shown to be of Damiida age, there was sufficient presumptive evidence
to warrant an appeal for assistance to determine its positive value.

An agreeable surprise awaited me in the responsive readiness with

operations, he furnished all the necessary sinews of war.

The expenditure up to the present amounts to something over
R34,000, of which R25,000 have been absorbed
by salaries and labour in nearly equal portions.?

very little indeed regarding the groups of the Géndwana rock-system. On the map then
published (1859), Umaria (Omria) is on the lower Dama, i.e., the true coal-measure rocks
(Memoirs, II, part 2, p.171); but so also were placed the undoubted top Géndwana beds
(Jabalptr) on the Méhénadi. In 1868-69 I made a traverse of all these rocks between
Hazaribagh and Jabalptir, and then detected the Talchirs along the gneissie promontory
north of Umaria. In 1871-72 Mr. Hacket undertook the detailed survey of that ground
with the new large-scale maps. His work was so manifestly incomplete and faulty, all the
rocks from the Méhdnadi to Pali on the Jéhilla being coloured as Jabalptr, that it was con-
demned as useless. Thus, the age of the Umaria coal was very much an open question
when Mr. Hughes took up the work which he has completed in so thorough a manner.
It is very good of Mr. Hughes to distribute to others the professional credit that is vir-
tually all his own; to find fossils when one is told to look for them, is a very small contri-
bution towards the final result.—H. B. M.

helpless without Captain Barr’s aid, and the end of our researches would

working in the interest of the Rewah State ; the professional reputations
of all were at stake, and they would have been seriously impaired if
apathy on the part of the Political Agent had prolonged the term of

troubles should properly be placed. The maps are now fifteen to twenty
years old, and considerable changes have taken place since they were
completed.

The task of writing this memoir has been committed to my care, but
the observations embodied in it are the result of the joint labours of my
colleague Lala Hira Lél and myself. At the outset of the survey, he
was entrusted with the examination of the Metamorphic, Talchir, Laméta,
and Trappean boundaries, but during the last two seasons he was appor-

important task of prospecting for coal and tracing
the limits of the Bardkar group in the Koréa and Jhilmili States.
Without the aid that he ungrudgingly gave, it would have been most
difficult in face of the many interruptions that I-received to my more
legitimate work, to have completed in so short a time the survey of the

large area which engaged our attention.

SECTION II.—PHYSICAL DESCRIPTION.

The area described in this memoir forms a portion of the great
central basin of Géndwana rocks occupying a large part of the country
drained by the Sdn and some of its southern leading tributaries and
principally comprised within the limits of the Rewah State.

In touching upon the various physical and geological features, I
have been guided in selecting a starting-point by the circumstance that

Deseription proceeds the western end of the basin is nearer to the
from west to east, "station of the East Indian Railway, whence our
annual departure for our season’s work took place. It would have been
as easy, so far as describing them was concerned, to have commenced in
the east, but this would have been an inversion of the order in which
the survey was actually carried through.

The range of our observations extended proximately for a distance
of 150 miles from Long. 80° 45’ E. to Long. 82° 55’ E., and I have
been able to add the link required to connect the
investigations of MM. Hacket and Mallet in the

Area surveyed.

Jabalptir district, with those of MM. Ball and Griesbach in the Gurjat
States of Chitia Nagpur.

The limits to the west and east are the two tributaries of the Sén, the
Ma4hanadi! and the Rér; the boundary to the north is the boundary
of the supra-Bardékar rocks, and the extension southwards is demarcated
by a varying fringe of stratigraphical deposits. As thus defined, the
different rock formations oecupy an area of nearly 3,200 square miles,
of which about 870 are included in the zemindaries of Koréa and Jhilmili.

comprehensive and convenient one that has been
proposed, and I would certainly retain it in preference to amplifying
for the mere purpose of including the territory which is beyond the fiscal
limits of the Rewah State. Mr. Ball gave the separate name of Jhilmili
coal-field to the coal bearing rocks of the Jhilmili estate, and Lala
Hira Lal proposed the designation of Koréagarh for a small outlier in
Koréa; but as these are integrant portions of the Géndwana basin,
they have been subordinated to the weightier claim of Rewah, as a
representative title, and-in this way share the lot of the Umaria, Kérdar,
Sohagpur and other coal centres.

its hilliness.

The chief highlands are, those to the north, marked by the famous
hill fortress of Bandégarh and the numerous detached peaks and lesser
ranges belonging to the same system, extending far to the east
and west beyond our area; the uplands of Koréa,’ the watersheds of
the Johilla, Sdn, and Hestho rivers, and the great plateau of the
Deccan (Dakhan) trap to the south. There is a gradual rise from west
to east, and from north to south. At Umaria in 80° 54’ BR, . Long.

and regular increase of elevation to 2,477 feet in the neighbourhood
of Sanhat, the capital of the Koréa State on 82° 25’ E. Long. The
loftier peaks, such as Bandégarh, Koréégarh, Mahéra, and the crests
of the Dakhan uplands, of which Amarkantak is one, are respectively
2,662 feet, 2,955 feet, 3,371 feet, and 3,400 feet high.

The hills vary in shape according to the rocks of which they are

at made up. Those of Baéndégarh and its associates

are usually flat topped with precipitous sides for
some distance down, and then a sloping termination of broken rocks and
stones to the foot, preserving a steady alignment for long distances or
sweeping in full curves. This is the characteristic form produced by the
sculpturing of the Mahadéva and other supra-Barakar sandstones, and
is quite distinct from the scarped facing of the trappean plateau, which is
much more irregularly eaten into, and has not the same prominent
accumulation of debris at its base,

The small independent hills, of trap, sandstone, or shale, have no
definite contour, and are narrow or broad, conical or lumpy, as the caprice
of Nature has determined.

The highlands to which reference has just been made constitute the

mee, watershed of several of the larger rivers of India,
Of these, the S6n more immediately concerns
us; as, though the Narbada rises in the Amarkantak plateau, a part
of Rewah, it soon passes into the territory of the Central Provinces, and
beyond the scope of our notice.
The Sén has its source in the Pendra table-land at an elevation of
2,100 feet, but it enters the Rewah State about 30
Hae miles from its origin, and a short distance above
its junction with the Kéwai. Thence it flows in a generally northern
direction, until it receives the Mahdnadi. At this point, in 24° 5’ N.
Lat., and 81° 5’ E, Long., it is diverted to the east, and holds that way
until it falls into the Ganges.
Its feeders in its upper course are quite equal to it in size, and in
fact the Kéwai, which has its origin in the uplands of Koréa, is a more
» important stream, and contains a greater volume of water.

nadi, and the Rér. These two latter rivers, how-

ever, join the Sdn outside our ground, and consequently they appear on

the map as independent streams. The Sdn is the essential river of the

Rewah State, and it drains the whole of the Géndwadna basin with the
exception of the part in the Koréa zemindari,

There, the Hestho and the Géj constitute an independent drainage

nadi which empties itself into the Bay of Bengal.
The watershed of the two systems is coincident with the territorial
boundary between the Rewah State and Koréa, but that the uplands of
the latter State should be apportioned to a drainage basin other than
that of the Sdn seems an invasion of the latter’s rights. A glance at
the map certainly produces the impression that the Hestho has been
needlessly intruded into the confines of the Sén basin, as both to the
east and to the west of it the neighbouring streams are tributary to the
Son. The waters of the Hestho and its tributaries wend their way
southward, in direct contrast to those of the Sdn and its feeders, which
flow northward.

In many places the scenery is exquisitely charming, the hilly nature
of the country that the streams run through lending itself especially to
the indefinite multiplication of varied prospects. In the Jéhilla, that
takes its rise near the sacred source of the Narbada, and flows to the
lower level of the Géndwana basin, there are reaches as romantic as its
own mythological story,’ where it coyly steals in view, struggling slowly
as it wends its way through overshadowing jaémun and fringing
tamarisks, and then gathering strength in some narrow gorge, it dashes,
flecked with foam and to the music of its onward song, a candidate
for our admiration. ‘There are several falls in its course, but their

height is not great enough to make them imposing, and during the cold
weather, which was my only opportunity for seeing them, the water
passing over the dark basaltic sheets of the river channel was too
attenuated to be a pronounced embellishment to the sombre background
of the picture.

In the Hestho, and most of the streams directly and indirectly con-
nected with it, there are some very striking water-
falls, and in the statistical account of the Tributary
States of Chitia Négpar, edited by Dr. W. W. Hunter, Vol. XVII, men-
tion is made of one of the finest in the Hestho near the village of Kir-
| Kirwshi falls—see W4hi.! A large volume of water is precipitated, and
froneiapieve: the sound of its falling can be heard for a long
distance on a still evening. A representation of it from one of my own
photographs forms the frontispiece of this memoir.

In the Kéwai there are long reaches of much-eroded sandstone, and
the appearance of some of them struck me as being of sufficient interest
to form another illustration of fluvial scenery.

always a nursery for the worst form of spear
grass, and for the several years that we have been engaged in tracing
the boundaries of intrusions or overflows of voleanic origin, we have
been compelled, where accuracy was a matter of necessity, to delay our
examinations until the season was well advanced, and spring fires and
migratory herds of cattle had assisted to clear the ground of this unwel-
come hinderance to geological research. In all instances where I have
been forced into contact with this baneful pest, I have deemed it a duty
to inveigh against it, but no emphasizing can convey a proper sense of
the condemnation that it deserves in the south Rewah and Koréa
district. In the cold weather it possesses the charm of greenness ; but the
feeling of pleasure that this gives rise to is dashed by the disappointing
knowledge that every stalk is armed with a sheaf of barbed arrows,

There is probably no sportsman who has not anathematised this grass,
and though an Indian geologist is wellknown as long-suffering and of
many virtues, I question whether there is one who could plead “ not
guilty ” of having consigned it to the region of Pluto.
Everywhere there is an abundance of coppice and jungle, but there are
oe very few blocks of fair-sized timber. During the
construction of the Great Indian Peninsular Rail-
way, the contractors for sleepers who rented the forests from the late
Maharaja of Rewah, Raguraéj Sing, cut and hacked mercilessly ; and
now some years will have to elapse before the trees that are growing
acquire useful dimensions. Of late, attempts have been made to induce
the native fief-holders to conserve woodlands, but they look upon the
suggestions laid before them as subtle traps to eventually deprive them
of their forest rights.
In view of the construction of the railway from Katni to Umaria, and
Scareity of largetim. ts future extension to Bilaspar, it would have
ber: been very convenient had there been a supply of
ready-grown trees fit for sleepers ; and though the requirements of mining
are less exacting, the existence of timber land near at hand would be of
great consideration in estimating the advantages of a given coal-field.
The most universal forest tree is the Shorea robusta or Saré, and it

which the special constituents of trappean matter preponderate. Its
place in this instance is taken by Boswellia or Sd/é and so frequently
is this a significant circumstance, that I have often been led to the
discovery of some dyke or run of trap by noticing the presence of this
tree. Probably there are many affections of this sort, but this is the
only useful one that I know of to the geologist.

of the country. These two tribes may be looked upon as the source from
which colliers must be obtained when the opening of the Rewah coal-
field on a large scale is decided upon. From my experience of them
during the past five years, I think the Baiga is to be preferred to the
Goénd, being more hardy by nature and more deft with his hands.
In the mines, the Baigds were certainly more fearless, as well as more
staunch to their work, ‘Their intelligence is of a low order, and they are
slavishly susceptible to the promptings of their village elders. They
have not courage enough to exercise their individual independence, and
for some time to come they will require delicate handling before they are
made to understand that coal mining is an occupation by which their
interests will be advanced.

there is very little to remark. The published

been compiled by the late Mr. J. G. Medlicott, and the geological lines
that he laid down correspond closely to my own. As my opportunities
for careful examination have been greatly in excess of those of any prede-
cesssor, I think it unnecessary to quote from them in order to contrast
the advances that have been made in our knowledge during the last
few years.

My researches have principally been confined to the coal-measures,
and it is to them that the present memoir is almost entirely devoted,
as the succeeding rocks still require further investigation before their
position in the geological scale can be categorically affirmed. Under com-
pulsion, I could, of course, assign a place to them, but I should have an
uncomfortable consciousness that my decisions were open to correction.

The evidence afforded by the plant-remains which are gradually being
collected, seems to point out a closer relation be-

Evidence of closer re- ,
lationship between the tween the contiguous groups than was formerly

ia allowed, and less stress must be laid on what were
deemed lithological characteristics.

This, however, is an alternative admission, depending upon the relative
value that we accord to lithological and paleontological evidence,
whether what were deemed mineral characteristics are to be subordinated
to the supposed fixed horizon of certain fossil plants, or whether those
plants are to have a wider range in time. In the Damida and Wardha

valleys the presence of ferrnginous matter was in some cases testimony
enough to determine the affiliation of the rocks, but this again was perhaps
due to the imperfect measure in which their paleobotanical resources were
explored, and evidence was passed bye, that might have tempered its

value as a decisive index.

IDENTIFICATION AND DISTRIBUTION OF ROCKS.

The Metamorphic series apppears occasionally along the southern

margin of the basin, between Lora and Umaria,

in the Johilla Valley, at Baghalwdri, where the
proposed railway line crosses the Basdr stream, in the south-eastern
part of the Sohagpdr district, and in Koréa and Jhilmili.

The inlier west of Umaria, forming the western shore margin of the
Umaria coal-field, is of considerable significance in any speculative
discussion on the facility of reaching the coal measures, presuming their
extension in the direction of the Mahanadi. The cropping up of the
Metamorphic rocks at Léra points to the probability that the floor of
deposition of the Géndwana formation is at a shallow depth from the
present surface.

The Bijéwars, represented almost entirely by silicious limestones, are
confined to the strip of land between the Mé4-
hdnadi and the Machrér stream. With some
modifications, the geological lines are those of Mr.C. A. Hacket’s map,

( 148 )

rest always on the Metamorphics. Their most westerly exposure is
in the neighbourhood of Kathai, and they run in a north-easterly
direction through Léra to Achala and Majgama and then turn south-
ward towards Baréri. Here they are overlapped by higher rocks, but
they reappear in the vicinity of Marodhi Chandwar and Paunia. Their
fullest developement is in the district of Sohagptr, and they extend
thence far to the sonth and east, connecting the Rewah area with the
Talchirs of the Mahanadi basin.

The identification of this group is perfectly easy, as it exhibits
with two local exceptions the same lithological features that charac-
terise it elsewhere. It seems gainsaying my own statement to assert

Sit that at one time I questioned the occurrence of
Télchirs at Lora. The point had been passed on
to me to decide, and at first I was inclined to think that the Talchirs
were absent. This was a misapprehension, but it was due entirely to the
fact that there were no sections open enough to decide a question that was
already surrounded by controversial assertion. Had I wandered away

north side they stretch from Pénri to Bara Chada. The bottom bed is a
fine-grained compact brownish-grey calcareous sandstone; then above
comes the famous boulder-bed, the matrix consisting of greenish-grey
silt; the contained fragments are red binary granite, conglomeratic
quartzite, quartzite and green schist. The bed is quite 80 feet, if not
more, in thickness. To this succeed claret-coloured greyish-green and
yellowish silts; one or two thin boulder beds; compact slightly cal-

in the opposite direction, until they are overlapped by Lamétaés and
Barakars. :

Leaving the valley of the Jéhilla and proceeding eastward, no
snereneen Talchir rocks are exposed until the edge of the
4 main body in the Sohagpur district is reached
near Tiirri at the base of the trappean plateau. Here they are made up
of the same varieties of beds as occur in the Damfida valley, and the
green and yellowish silts are the predominant rocks. Excellent sections
of them are visible in the Sdn, the Hesia, the Alan, the Tipan and other
rivers ; and in several places I procured fossil ferns.

There is a local modification of some of the sandstones, which I think
might mislead an observer who approached them with the ordinary
T4lchir panorama before his eyes.

Their appearance at all events was questionable enough to raise, in my

Sandstones, modifica- Clleague’s mind when mapping them, a doubt as
tion—near Nindauan. to their true affinities. They occur on the isolated
hills east of Nindauan and are compact and vitreous-looking, like
quartzites ; added to which, the accident of their resting on metamorphic
rocks, and being represented where first seen by a slight thickness,
strengthened the idea that they were members of the metamorphic
series. On examining them carefully, however, it became evident that
they were sandstones with the texture distinctly granular, not in the
slightest degree crystalline, but rendered close and hard by calcareous
matter. Eventually, decisive evidence of their specific character was
obtained in one of the streams near the village, where they were found
overlying a boulder-bed.

Throughout an extensive tract in the southern part of Koréa and

k Jhilmili, the Talchirs are displayed in great force,
on and many of the higher hills are partly constituted
of them. The boulder beds are more heavily weighted than they are in
the west, and as a whole the group is of more importance. The litholo-
gical characteristics, however, are unaltered, and it is therefore unneces-

sary to dwell upon them.

There is satisfactory proof of the occurrence of this group over a
large portion of Rewah, Koréa, and Jhilmili in the strong resemblance
that its sandstones and other rocks bear to the typical representatives in
the Raniganj field. Included with it are the beds containing a flora
which partly coincides with that of the Karharbari group. I saw no

logical grounds, for separating them from the Ba-
rakars, and consequently I have not mapped a line of demarcation. This
may be a misfortune, so far as it fails to be in harmony with the restricted
application of the paleontological facts, but as the wider bearing of the
evidence demonstrates a closer knitting of all the groups than has hitherto

been admitted, I am not yet ready to allow, in the absence of other
testimony, that a sub-division of the Barakars is a necessity.

The same remark applies to the upper part of the group, where
one or two plants may be referred to upper-Damuda forms.

By far the most abundant rock is, massively bedded yellowish-grey

aes felspathic silicious sandstone, that undergoes muta-
tions due to different degrees of decomposition in
the felspar, to the presence of caleareous matter, and to the changing size
and relative proportions of the felspar and quartz grains.

Shaly sandstones and shales bear an insignificant proportion to the
whole, and carbonaceous shales and coal are rare, though essential consti-
tuents of the group. Pebbles are not so frequently present as in other

localities, and there is an entire absence of the

to the main body, which occupies a superficies of 1,587 square miles, the
other areas are outliers of small extent, but the accident of geographical
position has made the two westerly ones the most important economically,
so far as immediate commercial considerations are concerned.

One of these is the Umaria coal-field, of which I have already written
several notices, and on which the interest attaching to the coal resources
of the Rewah Géndwana basin has for the last few years hinged. As it
takes precedence in order of situation, according to the plan of descrip-
tion already adopted, IT will refer to it in detail first.

SECTION VII.—THE UMARIA COAL-FIELD.

This name has been adopted from the village of Umaria, which occu-
ec pies a nearly central position in the field, and is

a place of considerable importance. It is on the
high road from Mtrwara to Sohég par, and contains nearly 600 inhabit-
ants, a permanent bazaar, police station, post office, and a forest out-
post. A weekly market is held, and since the establishment of explora-
tory coal operations, traders of all descriptions have been attracted to the
spot.

It is situated on the left bank of the Umrar river, a tributary of the
Mahanadi, and is distant 36 miles from the station of Katni, on the East
Indian Railway.

The most noted local points of reference are the fort of Bandogarh, 16
miles in a north-easterly direction, and the towns of Kauria and Chandia,
situated respectively in latitude N, 5°" and longitude E. sa and
celebrated formerly for the manufacture of native arms.

The field occupies moderately level ground, but along its western
border is a low range of metamorphic rocks, and to the south and north
are other hills composed of different formations. They assist in giving
to the neighbourhood of Umaria a very picturesque aspéct, and as there
is no lack of trees and coppice, the scenery is in striking contrast with
the cheerless coal-fields of Bengal.

The Umrar is the principal river of the district: it rises in the trap-
pean plateau to the south, and enters the area of the
Bardkar rocks a little above Kalésar. Where it
flows past the village, it is confined between rocky banks, sufficiently
high to be noticeable. A somewhat imposing-dwelling-house belonging
to the local Baghél chief, Chathar Dhari Sing, has been built on the
cliff overlooking the stream; and certainly credit is due to whoever took

advantage of the situation ; for, during the cold weather, when the bed of
the river is still moderately full, and ferns and other plants and climbing

not appear to hold much water. Most of the rain that falls is evidently
carried away at once, as there is a very thin capping of soil to gather it.

mapped them as suggested by the evidence that was
available. The contacts with the upper and lower groups are all na-
tural. The Talchirs are overlapped, where the Bardkars rest upon the
metamorphic rocks of the Léra inlier, and the Barakars themselves are
irregularly overlaid by newer Gondwana groups.

To the south-west of Umaria, the lower limit of the group is fairly
recognisable, and the borings near the railway track indicate that the
lines shown on the map are passably accurate. Near Chatén and Lél-
pur there is more satisfactory ground, in the clearer views obtainable of
the beds, for belief in the correctness of the limitation adopted. To the
east of Umaria, however, and within the Kélésar holding, there is a
broad margin of uncertainty, as the surface soil effectually hides every-
thing from view. While opportunity offered, I had three borings put
down in order to test the extension of the coal measures in that direction,
but unfortunately a series of mishaps prevented their completion, and the

question is still an open one as to how far eastward the boundary ought
to be placed.

There is no continuous section showing the arrangement of the
group, but a very fair idea of the stratigraphical sequence may be obtained

rohi downwards to its junction with the Umrdr, and then onward in the
latter river to Kalésar, Umaria and Lélpir.
The lowest bed of the Bardkars in the rivulet referred to is a slightly
1 eg eee ferruginous-tinted, felspathic silicious sandstone.
Above it is a thin band of coaly shale, and then
a succession of laminated sandstones, argillaceous blue carbonaceous
shales and thicker bedded sandstones, some of which are fine-grained,
faintly salmon-coloured, slightly micaceous rocks. Near the temple of
Dévi, and higher in the series, is a seam of coal of very good quality,
but measuring only 14 inches, which puts it out of consideration in an
economic summary. The dip is N.N.E. at a low angle of 5°. At
the elbow of the stream, above its junction with the Umrdar, are some
slightly carbonaceous grey argillaceous shales, in which the fossils were
found that determined the true age of the Umaria measures. Then
follow thick-bedded light grey tinted sandstones, flushed with a pinkish
hue and stained in portions on the outside rusty yellow. In the
Wardha Valley field this colouring would have been the peculiar mark
of the Kamthi series, but in the Rewah Gondwana basia it has no

specific significance.

These sandstones, with a varying proportion of caleareous matter, are

near the village of Kalésar, and the Umrar flows through a short but
pretty gorge, where an excellent view of the rocks may be obtained.
Intercalated with these sandstones are the various carbonaceous layers
that give value to the Umaria coal-field.

In the Umrar river, however, only one seam is visible, and the refer-
ence that I have just made in the plural number is due to the light

thrown upon the constitution of the field by the various borings.

of this stream, where it is reported that a seam has once been on fire. I saw no sign of
such an occurrence.

UMARIA COAL-FIELD. Q1

From Kalésar to the upper boundary of the Barakars*ygtween Uma-
ria and Lalpdr, only sandstones are seen, at intervals of varying
distances. They differ but slightly from those already alluded to ;
the highest beds are grey and pinkish coarse-grained felspathic sandstones
partly decomposed and with thin lenticular shaly layers. To these succeed
the red and other coloured clays of the supra-Bardkars, from which the
village of Lalpar is probably named.

Though there are several different courses of coal, I failed to find
more than one outcrop in addition to that alluded

to near the temple of Dévi, and that was of the

seam exposed in the Umrar at the southern water-ghat of Kalésar

in which quarries were eventually opened. It can be traced on the left

bank of the riverin a little rivulet, which is shown on the annexed map,

exhibiting the environs of Umaria-Kalésar, on a scale of four inches

to the mile. After extending about 200 yards to the westward, it is
lost to view.

Many years have elapsed since the original discovery of this coal.
The first who drew attention prominently to it was Captain Osborne,

eae Grank, the Political Agent of Rewak in 1860, and on his
and Captain H. Hyde, representation, Mr. Alexander Grant, of the East
Indian Railway, and Captain H. Hyde, R.E.,
Consulting Engineer for Railways, visited Umaria and other localities
where coal was stated to occur, Their recommendations were opposed
to any active steps being taken to explore the field. Mr. Grant, in his
report, stated—“ The seam shows itself in four different places in the bed
“and sides of the Umrar, a little above the village Kalésar. It is in
“all about 3 feet 6 inches thick, being made up of thin layers of carbon-
“aceous shale of different degrees of consistency and different shades of
“ eolour, some of them being indurated, others earthy, some black and
“others bluish. Amid them is one band or layer of some 6 or 7 inches
- “in thickness of the substance resembling coal evidently in greater

“part of vegetable origin, and what we have seen to be combustible.”
There was some excuse for the low estimate they formed of the value

of the Umaria seam, owing to the washed-out and dull appearance of the
coal at the outcrop. but their conclusion drawn from inadequate investi-
gation shows how dangerous it is to frame an adverse opinion of the
quality of any coal until careful analysis and experiment have proved
what its composition and real worth are.

Subsequently at different times the existence of the seam was again

bat dlNaunreyane ene noted by some of our own officers, but no regular

rath survey of the coal deposits of the Rewah State

was instituted until the season of 1879-80. Late in May 1880, I obtained
without visiting Umaria some samples of coal from a few inches below
the outcrop. These were submitted to assay by Mr. Mallet, the Curator
of the Geological Museum, and the average of his determinations gave
a sufficiently favourable view of the quality of the coal to prompt a more
searching investigation when the opportunity arose.

The figures were—

The ash was much less than I anticipated from the appearance of the
samples, but the amount of moisture was high, and as it confirmed in a
measure the opinion then held of the age of the coal, I deferred a closer
examination until the mapping of the known areas of Baradkars had
been completed.

It was not until November 1881 that in the ordinary course of the
general survey it came under my observation. The first field day was
enough to make me suspect that the sandstones and consequently the
coal with them were much older than had hitherto been supposed ;
and, acting on this belief, I endeavoured to obtain confirmatory
paleobotanical evidence. The credit of supplying the direct proof of the

Discovery oft plants by horizon of the coal-measures rests with my colleague,

than myself, was the first to have his efforts rewarded by the discovery of
a few plants of specific lower Gondwana age.

Recruiting the services of my personal servants, and stimulating their
zeal by the promise of reward, we eventually obtained several fronds of

Glossopteris communis.
Gangamopteris cyclopteroides, var. Ape

None of the fossils were perfect specimens, as they occurred in friable
slightly carbonaceous argillaceous shale, which it was difficult to handle
in a satisfactory manner, but they were sufficiently distinct to enable
Dr. Feistmantel to fix their genera. With the assurance that the proper
place of the Umaria coal was with the true or older coal-measures of India,
Thad no hesitation in spending a small sum of money to clear the outcrop
and obtain a clean piece of coal. Selecting an average sample from the
lower portion of the seam, the percentages of ash, fixed carbon, and
water showed so great an improvement on the first analysis, that I was
impressed with the desirability of drawing the attention of the Rewah
administration to the fact of the occurrence of true coal-measures at

Umaria, and that if arrangements could be made

for practically exploring the field by boring, I
should be happy to render what service I could in directing operations.
Fortunately for the furtherance of my views, Captain Barr, the Political
Agent of Rewah, responded cordially to my suggestions, and within a few
weeks of my broaching the plan of operations, the necessary plant was
purchased, and Mr. Stewart, who had previously been in charge of the
Narbada trial borings, was appointed to test the various sites indicated
by myself. There is no mechanical establishment in connection with
our own department, and there is no such thing as a grant for independ-
ent explorations, so that, had the Political Agent for Rewah put aside
my communication, it is probable that the Umaria coal-field would once
more have been dropped for a period of years into the shadow of
obseurity.}

Government of India would have done so on the strength of Mr. Hughes' recommenda-
tion.— H. B. M.

satisfactorily indicated the occurrence of coal over a sufficiently large area
to supply several million tons of fuel.

On the other side of the river, five borings were started. Two of
these proved coal, but a series of misfortunes rendered the holes between
Kaélésar and Lalpir useless as indicators, none of them having been com-
pleted. The question, therefore, as to what becomes of the coal in that
direction is an open one, but I incline to think that the coal is there, and
that, had the borings been carried deeper, they would have proved
this to be the case.

separated by 25 feet of carbonaceous sandstone were passed through
at 184 feet from the surface. It is possible that these measurements
may not be quite exact, for the readings of coal and shale may be so
influenced by the desire to tell a promising tale, that the latter is
often unduly elevated to the dignity of the former; but I think it
would be inconsistent to accept one journal as correct, and doubt the
accuracy of another. Boring records are generally trustworthy enough to
establish the broad fact of the occurrence of coal, though considerable
caution is necessary when accurate discrimination of coal and shale is
demanded.

The boring No. 9*, which was really a test of No. 7*, and put down in
November 1883, was most carefully supervised and a lower seam was
met, so that we may fairly accept as proved that there are two.

Considering all the facts that were established during the first stage
of our practical explorations, I think it must be confessed that the labours
of the Geological Survey were eminently satisfactory ; coal was proved to
exist in abundance, that it lay within easy access from the surface,
that it thickened to the deep, and that the gradient, as shown by
the horizon at which the seam was struck at various points, was low and
advantageous for working.

Every circumstance was promising, and from the exceptionally
commanding geographical position of the field, it required small advo-
eacy to show that a splendid reserve of fuel had been unearthed in the
Rewah State.

In order, however, to set at rest any apprehensions that prudence or

experience suggested, it was deemed well that they should be reduced to
their smallest limits, and, to achieve this object, it was determined that
the coal should be approached under the ordinary conditions of approved
mining. ‘There were two plans open for adoption,—either to drive an
incline from the outerop, or to sink a shaft to the seam. The second
method was preferred as being in every sense more workman-like,
and as affording more scope for efficiently dealing with an influx of
water.

On the 1]th March 1883 a pit of 10 feet internal diameter was

was only to meet a temporary demand for coal, while the trial pit was in
progress.

As special qualifications were required for the charge of the contem-
plated underground expansion of our operations, Mr. Thomas Forster,
who had gained his experience of colliery work both at home and in the
Bengal coal-fields, was engaged as Mining Engineer.

The position selected for the pit was near hore-hole No. 8, where
the section is somewhat in accord with Nos. 9 and 77—an upper and a
lower seam of coal having been cut in each.

The depth of the shaft was calculated at 108 feet, and the sinking
did not seem a very formidable task. It was not completed, however,
until May 1884. During the sinking there was no difficulty in dealing
with the water, a pair of ordinary buckets being quite sufficient to keep
the pit dry ; but the moment the coal was reached, a rush took place, and
though baling was kept up unremittingly day and night, it overpowered
the means we had at our disposal, and the pit was abandoned until more
efficient power could be applied.

without any extra machinery to combat the anticipated influx of
water, it was looked upon as rather a hopeless undertaking. Strange
to say, however, the measures in this part of the field were unusually
dry, and the coal was reached just before the close of the past season
without any other difficulty to overcome than occasional scarcity of
labour.

There was not time enough to drive into the seam, so that the only
objects achieved by the completion of either shaft were the procurement
of more perfect samples of coal and the more exact determination of the
thickness and constitution of the main seam than that afforded by the

Such a certificate as this speaks for itself, and from the first analysis

the only coals of Bengal that can surpass it are some from the Kar-
harbari field.

eventually an incline 6 feet high and 8 feet broad was driven in on the
chance of its affording direct confirmation of the augmentation indicated by
the borings. Following on this, a considerable impetus to the extraction
of coal was given by the acceptance on the part of the Great Indian Penin-
sula Railway of a tender in March of the present year for the supply of
2,000 tons of coal. As neither of the shafts at that time had been com-
pleted, a second incline and several cross-roads were opened out, which
enabled the raisings to be increased from 3 to 15 tons a day.

Throughout the workings the seam retains nearly, though not quite,
the thickness that it has at the outcrop. I give for comparison the

The roof is a tough, strong carbonaceous shale, and in appearance
isnot unlike the d band. It has stood excellently,

and not a single piece of timber has been required

to support it.
The dip is very low, which is a favourable point in the estimate of the
Dies value of the field, scarcely rising above 4° in the
inclines. Its direction is nearly north-east.

The quality of the coal wrought in the quarry and in the inclines
has been strongly tested under various conditions, but I intend reserving
my full remarks as to its effective character for the Economic chapter of
this memoir.

In anticipation, however, I may observe that the lowest 2 feet and
the bright coals constitute the best portion of the
seam; and that the hard band d would have to
be picked out, as it readily forms clinker.

Band d, clinkers.

The area over which coal has been proved may be accepted as 1}
Proved coal area 1; Square miles, but it will -be quite legitimate
square miles. to assume that the underground extension of
the measures in the direction of their exposed dip will give a far
higher figure for probable coal lands. I think it quite possible that they
extend uninterruptedly to the northward, dipping beneath the supra-
Barakars and appearing again, as the Kérar coal-field. With reference to
the Johilla Valley, I scarcely like to venture even an opinion; the dis-
tance between the two coal-fields is 12 miles, and the intervening
stratigraphical evidence is altogether too meagre to make any statement
on the subject of their continuity other than an idle guess,

SECTION VIII.—THE KORAR COAL-FIELD.

The next outlier of Bardkars to be described is 3 miles from the
nearest margin of the Umaria coal-field and to the north of it. It has,
in default of a better name, been alluded to in our manuscript reports as
the Kordar field. There was no natural feature distinctive enough to
suggest a title, and so the village nearest to the locality where coal was
most conspicuously exposed was adopted as the distinguishing appellation,

the Loéra metamorphic inlier. The boundaries of
the Barakars are fairly well seen, and the supra-Bardkars are too distinct
in character to leave any doubt as to their identification, so that the
separation between them and the coal-measures is easy.

Several streams traverse the field, and one of them is the Umrar. Its
; confluence with those flowing from Baréri,
River Umrar, P

Margtri, Gagrar, and Damokar marks the upper
limit of the Bardkars.

The major portion of the field has been cleared of jungle, but
adjoining it there are several plots of underwood, and more especially to

egy Ps the north of Dudraunri. Near at hand are the

reserves of the English Forest Department, coin-
cident for some distance with the boundary of the Rewah State. I
have no doubt that they can furnish some useful timber, and this
will be a convenience of no small consideration when a colliery is
started.

There are numerous sections of the Barakars, but the most complete
views of them are in the neighbourhood of Kéraér, Dudraunri, and Achala.
The rocks consist of grey and yellowish somewhat porous felspathic
sandstones, occasionally micaceous and sometimes calcareous, associated
with beds of carbonaceous shales and coal. A large sheet of trap,
varying in width, runs nearly the entire length of the field, and there is
an inlier of the Talchir group between K6étalwdr and Khaira. The
general dip is to the north.

Notice of the existence of coal in the Kordr field was originally
brought to us when encamped at Baréri by the landlord of Bardauha,
but it was not professionally confirmed until my colleague, while tracing
the boundary of the trap eastward of Tali in December 1882, saw and
mapped the different seams.

There are several outcrops, but there is only one main carbonaceous
horizon, as in the case of the Umaria field.

( 166 )

The most westerly exposure is to the east of Achala in the Umrar at
the village water-ghat. Two small bands show in
the banks of the river; and in order to find out
whether they increased in thickness to the dip, directions were given to

tion of further enquiries ; each point progressively fixed as coal-bearing
being the presage of additional success.

Umaria measures is to my mind a fair gauge of the structure and
composition of the Kérar coal-field, and hence we may assume that
there is one main coal-bearing horizon with a like minimum thickness of

workable coal.
SECTION IX.—THE JOHILLA COAL-FIELD.

The Bardkars of the Johilla valley are exposed about 13 miles south-
east of Umaria, and constitute two separate tracts, one to the north, and
the other to the south of the metamorphic exposure of Péuri. By far

the larger of the two, and the only one important from an economic point of
2 view, is the northern area. In consequence of this

prepare a map of each of them on an enlarged scale.
The accident of position has caused much more attention to be
devoted to the Umaria than to the Joéhilla field; but at the outset of
the Rewah coal explorations, not knowing what the fate of our purpose at
Umaria might be, a few borings were simul-
taneously carried out in the Johiila valley with
the object of testing the value of the signs of coal that were there
visible. The extra distance would have been a very small drawback if
the only alternative of procuring coal had been the opening up of that
part of the district. As events have shown, there was no immediate

necessity to have taken the precaution of examining the Jdéhilla valley,
but nothing has been lost by the course then pursued, and it is a matter
of congratulation that we have acquired definite knowledge of a further
and extremely valuable stock of coal land.

The rise of the Jéhilla river has already been described as being in
nAeyS the high trappean plateau of the Mandla District.
Jdhilla river, c :

It passes by a succession of descents into the lower
level of the Singwara division of the Rewah State, and, after winding
through a narrow valley known as the Khéli, which formerly enjoyed,
and even now, though in a less measure, an inviting reputation as a
splendid tiger-ground, exposes near Lakhanpara, 81° 6’ E. Long., and
23° 17’ N. Lat., the thin strip of Barakars that forms the south portion
of the Johilla valley coal-field. At Mangthar it passes through Talchirs,
and then soon after enters the metamorphic area of Pénri, the rocks of
which constitute its channel for 2 miles. A little to the north-east of
Pénri, it strikes the southern boundary of the Talchirs connected with
the northern division of the Jdéhilla coal-field, and then, flowing past
Bara Chada, offers from that point to its union with the Sén, the most
typical section of the Barakar and supra-Bardkar rocks that can be
found in the whole district.

I think it unnecessary to defend the propriety of the designation
Jchilla coal-field. There are no other exposures of the Barakar
group than those already alluded to; and as the southern area requires
only a brief notice, it may be dismissed in a few words.

South area.—Johilla Coal-field.

The measurement of its area gives 34 square miles, which is a magni-
se tude quite enough to make it a valuable field, if

coal occurred in workable thickness.

There are no out-crops, however, of any promise, and though I have

out-crops, I am now speaking with the knowledge acquired in the

CLO: 4

Umaria and Koérar fields. There, the main coal occurs well up in the
measures, but the difference here, so far as I could judge, lies in the

circumstance that the rocks are all below that horizon.
I would not discourage any who may, years hence, wish to satisfy

This portion of the coal-field extends over an area of 114 square
ans miles distributed on each side of the Jéhilla river
and forming a band of varying width between the

Talchirs and the supra-Barakars.

drawn to the fact of the occurrence of coal in

For travellers progressing eastward, Pali is the last village at which
supplies can be procured; and there is a great temptation to steal a
day in one’s programme of marches to enjoy the shady mango groves,
the beautiful prospect, and the wild duck and snipe-shooting that the
large tank and rice-runs afford,

In 1840 Dr. Spilsbury, in the Journal of the Asiatic Society of

Bengal,’ mentioned coal as being found in the bed

of the Geological Survey of India, Vol. II, Part 2, a short paragraph

concerning coal near the village of Malidgura, and mentions that it was

I believe that in the running trials the Jéhilla coal was stated to have
shown a slight superiority, but it is difficult to reconcile this assertion
with the deduction to be drawn from the analyses.

Considering the distinct advantage in fixed carbon possessed by the

Below the junction of the Bichna and the Dhébghata, there is a band
of coaly shale, but no coal. In the bed under it some specimens of
Glossopteris were procured.

In several places plants were discovered. Three species were obtained

Dr. Feistmantel points out, with reference to these forms, that
they correspond to the association of fossils found with the second and
third seams of the Karharbari coal-field. That there is this correspon-
dence is clear enough, but I have hitherto failed to see anything dis-
tinetive enough in the character of the rocks containing this partial
Karharbari flora to warrant a separation from the Barakar.

Before closing my remarks on the Johilla field, I would wish to say
Repedioner ee weirs that these explorations are another illustration of

researches by boring’ operations, for, like those who
preceded me, I formed a poor opinion of the seam from the evidence at
the out-crop. Greater experience of the frequent fallacy of surface indi-
cations enabled me to guard myself against expressing unequivocal
condemnation, but the general bearing of my opinion was, ? as expressed
in my first contribution on this area in the Records of the Survey, that
the coal was poor, and not worth much consideration. The borings and
quarrying have proved that something more practical than hammer tap-
ping is required to frame a correct estimate of the value of a seam.

It is fortunate that justice has been done to the Jéhilla valley, for,
notwithstanding the fact of its coal being 13 to 14 miles further from
Katni than Umaria, it will prove either a very formidable rival to that
field or a seasonable reserve, according to the conditions on which the

There appears to be quite 20 feet of coal, and, although the out-crop
of the seam cannot be traced for more than 2 miles, it is almost a
certainty that both in the direction of Khodargaon and of Pali shallow
sinkings would touch it.

I refrain from attempting to make a close estimate of the available
Ecce ee quantity of fuel, for there ne undefined area
under the supra-Barakars which introduces such
latitude into one’s figures that to my mind there is no satisfaction in
treating the question. If asked, however, whether 100,000,000 tons
of coal might be extracted from the Johilla valley down to a depth of 500
feet, I should reply in the affirmative.

1 “Records, Geological Survey of India, 1881, Vol. XIV, Part I, p. 127,”—“I do not
condemn it because experience has taught me that many seams (as in the Wardha and

Méhp4ni fields) with thin outcrops may thicken rapidly, and furnish a good deal of coal, I
can say, however, that the signs are not promising.”

SOHAGPGR COAL-FIELD. 41

SECTION X.—THE SOHAGPUR COAL-FIELD.

From the description of the three small outlying fields, I now pass
Afataaceatl Gordan to the notice of the more extensive main area
miles, comprising nearly 1,600 square miles, and to which
I would give the name of the Sohagptr coal-field. It may hereafter be
found convenient to introduce some restricted local designations. The
portion within the Koréa district appears suggestive of such a course, but
T have no doubt that the adjustment of names and titles will be satis-
factorily carried out when the necessity arises.
Roughly speaking, the Sohagpur field stretches through two degrees
of longitude, from the river Sén to the river Rér. There is no great
Coal seams not plenti- ichness of coal, nature having apparently exhausted
ful. herself in abortive efforts resulting in carbona-
ceous or coaly shale, or seams too thin, according to the present standard
of working, to be mined profitably. Owing to the horizontality of the
strata, however, such seams as occur of available size possess the advan-
tage of extreme accessibility, and can be easily won over an extensive
area.!
Of the rocks constituting the Bardkars of the Sohdgpdr field, quite

Retactdes constitute nine-tenths are sandstones, of which the major

Yoths of group. portion are the ordinary grey or yellowish-grey
silicious sandstones, sometimes earthy and sometimes slightly calcareous,
with a small percentage of mica.

I have grouped the whole of the coal measures as Bardkars, rather than
enter upon the uncertain and equivocal task of separating them under
the divisions of Karharbari, Bardkar, and Raniganj. Amongst the
lower strata there are fossil forms which agree with many of those found
in the Karharbéri beds of the Karharbdari field, and in the higher strata
are a few plants which were formerly esteemed as distinctive of the
Réniganj horizon. Later researches, however, have shown that the

range of many of the supposed characteristic fossil forms is much greater

than was formerly supposed, and in the absence of collateral strati-
graphical evidence, I have preferred to retain all the coal-bearing rocks
under one denomination.

With the exception of the lowest beds of the group around Saranpar,
Dhémni, Amiliha, and Dhirauli, there is a common type of feature in all
the sandstones, until the unmistakable ferruginous sandstones of the
supra-Bardkars are reached. There is no representative here of the
iron-stone-shales group, which, coming between the upper and lower
coal measures of the Damiida valley fields, makes the separation of the
Damida series in that region a matter of extreme facility ; and though
it isa fact patent to every ordinary mind that where little or no disturb-
ance has taken place, lower beds must necessarily be older than upper
ones, there is nothing sufficiently distinctive either in the distribution of
the plants or the succession of the strata to call for further sub-division.

It would involve a tiresome rehearsal of a multiplicity of names

large map; from which it may easily be perceived that the supra- Barakar
and Laméta groups are unconformable to the Barakars, Nearly through-
out their entire extent the boundaries are natural, the only doubtfully
faulted portion being that in the Jbilmili area, where a fault was mapped
by my late colleague Professor V. Ball.’ I was not able to make an
independent inspection of this feature, but I assume that my views
would have been in accord with his could I have devoted enough time to
the study of the question.

area as 1,600 square miles, outerops were very sparingly met with,
and when this fact was understood, it became an obligation to explore
every stream, great and small, much more closely than was at first
contemplated.

In the comparatively level expanse of the Sohdgpir district, this
obligation was almost too scrupulously discharged. But in the hilly
tracts and uplands of Koréa and Jhilmili, the tax on our time was too
great, the streamlets and the runlets being overwhelming in number ;
and many of them, in which doubtless there are exposures, have conse-
quently been unheeded.

Entering the Sohagptr field from the west, through the picturesque
Marcha pass on the road between Pali and the town of Sohagpir, several
miles of sandstones have to be traversed, both with and across their
strike, before anything like a workable seam of coal is met with.

Following the proposed line of railway as marked on our map, there

mise of anything better below the surface.

The thickest of these is 2 feet, and it occurs in the Kaundb4hara
stream, a short distance above its junction with the one coming from
Semriha. It is much weathered at the surface. Northward from this
outcrop, the sandstones are thickly bedded porous rocks with decomposed
and undecomposed felspar, the former of which is of an unusually reddish
colour.

Specimens of the fossil Zrizygia speciosa together with Glossopteris
communis, Glossoptercs formosa, and Vertebraria indica, were found in
some variegated micaceous shales, and greenish close-grained micaceous
argillaceous sandstone, associated with the coal band exposed in the
Marna river where it flows past Sohagptr.

This is one of the few localities in which Zrizygia was met with. As
bearing on the unification of the Damidda series, this equisetaceous plant
is a very interesting one. In former years it was supposed to bea

With the object of determining this circumstance,

and the further question of whether it was the
probable representative of the Umaria band, I marked a spot fora boring
near Chachai, but, for the reasons previously explained as affecting the
other sites in the neighbourhood of Sohagptr, my purpose was not ful-
filled, A feeling of grateful relief, after a month’s close survey, at having
found anything like coal, made me at first estimate my discovery of this
seam a little too highly. Referring to my field notes, I see that I al-
luded enthusiastically to the coal; a more moderate view gives, I
think, a truer idea of its quality.

The outerop is confined to the Bakan Nadi, as there is not a trace of
it in any of the numerous streams either to the east or to the west of
the Sdn.

I searched carefully around Mariaras for further signs of coal, but

Water-borne coal in ~ could only find water-borne fragments in the

than 5 feet, and two smaller ones underlying it,

all the different beds are repeated, and we must guard against over-
estimating the number of seams that we are dealing with.

It covers a large and easily workable area on either side of the Sdn, and
it can be picked up along its strike for a distance of 10 miles.

It is the seam par excellence of this part of the field, none other
approaching it in thickness; and I am glad to see that the line of

seam west of the Nargara river, and strange to say there is not a
vestige of coal exposed in the wide tract extending from the river to
the boundary of the overlying Laméta and supra-Baradkar groups to
the south-west. In the Sarpa Nadi, there is just sufficient coal to oblige
me to allude to it, but this is north of the area indicated as sterile.

The next tributary of the Sdn of noticeable size below the Bagéha
is the Kasér Nadi, which with its feeders gathers
the waters over a large stretch of country south
of the Kandk river, and the irregular line of trap extending from the
trap-capped hill of Mahdéra. There are very few outcrops of coal
within the limits of its drainage basin, and in two instances only could
I make a complete measurement of their thickness. To illustrate the

There is however one seam near Sahipdr which, though obscured by

Séhipir noticeable Water, appears worthy of attention. It crops out
ba where a small stream east of the village joins
the larger one coming from Karrabdn. About 4 feet are visible, but
probably 6 to 7 feet would be a nearer approximation to its true thickness.

About a mile below the Kasér is a little stream flowing from Birhdli

wines in which there is an inferior seam measuring 3
; feet, the continuation of one of those noticed
above. Then for 8 or 9 miles the Sdn flows over a considerable mass
of trap and through sedges which give the river bed an unusual appear-
ance of luxuriant greenness.

Near Nabalptr the Sarpa falls into the Sén. This stream rises at

the foot of the trappean plateau to the south, and

recelves a prodigious number of tributaries.

One of them between Hardi and Sérangpur exposes a thin band of
carbonaceous shale at a spot where several specimens of plants were
obtained. As this is the nearest and only approach to anything like
coal over a large area, I have noticed it. It has no significance, however,
from an economic point of view.

In another tributary,—the Jamina Baisaha—near Dhdmni, some

ore very fine leaves of Néggerathiopsis hislopi were
procured, and in association with them were seeds
of the same plant. “Of these latter, which Dr. Feistmantel has named
Carpolithes millert, he says, that they were first described from Passerabhia
in the Karharbéri coal-field from Karharbari beds. Jt is somewhat
interesting to find them in such a distant region as showing the wide
distribution of this particular cycad.

Enumerating the different collections of fossils from the neighbour-
hood of Dhamni, Sarangptr, and Hardi under one head as they all
belong to the same horizon, they comprise Vertebraria indica, Glossopteris
communis, Gangamopteris cyclopteroides, Gangamopteris spathulata, Ano-
mozamites, Néggerathiopsis hislopi, Noggerathiopsis lacerata, Voltzia
heterophylla, Carpolithes millert, Samaropsis, cf. parvula.

There is an analogy between these fossils and those from the Kar-
harbari group, but a recent visit to Karharbari has shown that, so far
as petrological and textural features are concerned, there is no harmony
between the rocks of the two fields. In the strata of the Karharbari
horizon, one of the points chiefly insisted on is the brecciated character of
the sandstones. Those of this region are peculiarly devoid of pebbles
either worn or sharp; they are principally soft earthy sandstones
and shales occasionally micaceous, moderately fine-grained, and either
whitish or grey dashed with pink or brown.

bability of its occurrence, that I chose two sites for boring ; one between

Khaira and Piparia, and the other at the junction

of the Bartia and the Sarpa streams, As I have
previously explained, however, these borings were not carried out, but
should explorations ever again be thought necessary, I recommend them
as suitable positions.

Tam inclined to believe that this seam corresponds with the shale
and coal east of Sohagpir along the border of the traps between Chainpa
and Jamtia-Jam6i, and perhaps if driven into, the proportion of coal at
both places may be found to be actually greater than appears at the
surface.

North of the Sarpa we find in the Sdn another outerop of what
struck me at first as being mainly carbonaceous or coaly shale, but it is

evidently the continuation of a large seam that is very plainly exposed
in the Nagaua and Jamtniha streams, and which, when accessible for
examination and measurement, proved to be a useful collection of
coal.

This seam can be traced over a very large area, and I am of opinion
that it appears again in the north in the Khairi and Kanak rivers. I
make this statement, however, with some diffidence, as the section across
country, although suggestive of this, is not a clear one. Analyses of
coal from the bands numbered four, eight, and ten give the following

results (ewclusive of water) :—

The better portions 4 and 8 are said to cake and partially eake, and as
the samples represent the worst quality of their respective bands, having
been taken from where the coal has undergone deterioration by exposure
to alternating heat and rain, we may confidently commend this seam as
a valuable item in appraising the merits of this part of the Soh4gpiar
field.

Higher in the series are two or perhaps three small beds of coal,
Small seams in various the outerops of which have been met with in
picts. the Nagaua and its tributaries, and also in the

strikes me as being of much importance; the greatest thickness in
no case exceeds 3 feet 4 inches. Several of the outcrops are at the

Seams at base of base of waterfalls, and whilst our survey was
PE progressing, this connection of coal with each
abrupt fall in the level of the rivers was found to be of constant oceur-
rence; during the later years of our labours, we took advantage of
this circumstance to diminish the toil of speculative wandering.

I am inclined to think, as I have already said, that the Nandnah
seam crops out at the mouth of the Khairi and Kanak rivers, but the
sections are very imperfect. ‘The first one, just at the junction of the

Passing again to the other side of the Sén, three coal bands occur in
me the Singaora and Silpari and Didpipar streams.

Outcrop in Singaora, :
Silpari, and Didpipar The largest of these is at the outfall of the Singaora
eas into the Son at the bottom of a small cascade ; but
like the rest it seems to promise nothing of practical value.

In the actual bed of the Sén, there is no sign of coal for many miles
down its course beyond the junction of the Singaora Nala, until the village
of Girart is reached ; but in the Marna river, which was alluded to when
describing the neighbourhood of the town of Sohaégpar, there is an out-

Mirna Nala, Bijauri CTOp between the hamlets of Udri and Bijauri. 1
Ouycror could not in any of my measurements make the
thickness more than 5 feet, and the quality struck me as being poor,
pieces of the coal being very heavy. One of the exposures is at. the base
of a small waterfall at the mouth of a rivulet joining the Mirna, and
while examining it I disturbed a fine male tiger (which I subsequently
shot) that had retired for the day to the cool enjoyment of an umbrageous
retreat.

The last seam of coal in the Sdn, and the highest in the series crops

after we had commenced the survey of the Sohagpir field. I could
obtain no information about coal from the natives; but by follow-
ing up the water-borne fragments for several miles along the channel
of the Son from the confluence of the Johilla, I discovered the source
whence they were derived. The following is the section -of the

If it were not that the distance between Girard and the Kunuk out-
fall was rather too far, and the evidence too imperfect to reduce correla-
tion to a certainty, I might be tempted to suggest that from the simi-
larity in the composition of the coal at these two places, the exposures in
both localities are of the same seam.

With this notice is ended the description of all the more important
outcrops of coal in the actual bed of the Sdn and the area drained in the
lower courses of the lesser tributaries that join it below Antkpur, after
the commencement of its traverse through the Bardkar group.

A large number of specimens of plants were found with comparatively
little trouble in the tracts of land enclosed by the
S6n and the supra-Bardkars, north of the latitude
of Nabdlpar. They were mainly of the genera Glossopteris, and Verte-
braria, and the latter occur in profuse abundance in many spots.
Quoting again from Dr. Feistmantel’s Fossil-Flora of the Rewah Gond-
wana basin,! the different forms determined, and some of the localities
whence a large proportion of them were procured, are—

species of Glossopteris are generally distributed, but others are restricted.
Schizoneura is more common in upper beds.

There are no specimens of Gangamopteris, and it is noticeable that
this plant is confined to the lower horizon of the Barakar group.

East of the Sén a very convenient division for details of other out-
crops may be drawn at the north and south watershed of the Kéwai river
and its tributaries, near east longitude 82°. Although the area is a large
one, there is a notable absence of thick seams, and indeed there is not
one exposure which at first sight would undeniably be declared valuable.
Almost without exception every outcrop was imperfect or indistinct,
Many of them were entirely under water, and their discovery was
chiefly due to having a graduated scale of liberal rewards which excited
the exploratory ardour of my camp. There was no opportunity of learn-
ing anything by boring, and the fact of coal occurring at Umaria and
being worked there made it appear unnecessary to expend time and
money in even shallow trenching.

Proceeding eastward from Gurard there are carbonaceous shales here
and there ; and some inferior coal south-east of the
village of Khama. The largest of these outcrops

is capped by rather coarse sandstone with a roseate tinge, and the
measurements are —

There is nothing inviting in the appearance of this seam, but it is

No coal is seen between this and the Obhi river, forming the bound-

any importance in the Kanuk or its feeders until nearing the village of

This is the most promising seam in this part of the field, and though

real underground relative thickness of the shale, I am inclined to form a
favorable judgment of its worth and to hope that the shale may diminish.
In the Kundk there isa 4-feet seam of moderate quality below the
RAE CORGCORS deen outfall of the Dhoran, and then there is along

appearance of true coal. As its head waters are neared, however, there
are numerous subsidiary streams, and in them, as also in the Kanik,
there are some outcrops of carbonaceous matter.
All of them, with the exception of a 3-feet seam of coal south-west

The Schizoneure occurred in grey olive-green shales, bearing resem-

Bae of the Réaniganj field. The Vertebrarie were
found north-north-west of Kanhér, in a bed of carbonaceous. and argil-

first instance in which I have ever met with roots or stems in such a
position, and on account of the rareness of the circumstance, I have
thought it worth while recording. There is every appearance of the
Vertebrariz being in their original situation, having grown in the carbo-
naceous shale, and penetrated into the underlying bed.

Outside the drainage system of the Kinuk, there is still one river,
the Géhirdri and its tributaries, lying west of the
watershed of the Kéwai, in which there is evidence
of coal, It joins the Sén within the area of the Talchirs, but throughout
its entire course it is the old story of no seams of a determinable thick-
ness of over 3 feet. There are outcrops near

detailed and more special enquiry is instituted. 1 deemed it a sufficient
reason, so far as this country is at present concerned, for abridging my
examination of a seam when its apparent thickness did not exceed 3
feet ; at the same time I am aware that beds of less thickness than this
are sometimes successfully worked in Europe.

Kéwai River.—The next observations on coal fall within the drainage
system of the Kéwai river, and there is some satisfaction in being able to
state that two or three of the outcrops met with rise above the yard
limit.

The Kéwai and the Sén meet about 24 miles below the border of the
Pendra subdivision of the Bildéspur District. Of the two rivers the
Kéwai is the larger, and its name should either have been substituted
for that of the Sdn, or the course of the latter should have been along
eae that of its affluent. The scenery of the Kéwai is

in many places very bold and impressive, there
being repeated stretches of rocky channels and cliffs of coal-
measure sandstones. The eroding action of water is remarkably illus-
trated in the form of pot-holes; and I have never

met with more striking displays in any of the
fields that have fallen to my lot to survey, than those which are to be
seen in this river. I have selected for this memoir a view near Gam-
bhirda of an area of erosion just within the boundary of the Bardkars,
where there are some cave temples, reaches of clear deep water, a succession
of small falls, and a lining of forest trees, in fact where circumstances
combine to make a varied and an attractive picture.

Proceeding up the Kéwai northwards, two thin bands of coal are ex-
posed between Pasdn and Gambhiria, but the first fair-sized seam occurs

iy west of Bélha Paiari. There are several exposures

it will be at once seen from the high amount of fixed carbon in it that
this seam may be adjudged a good and useful one.
A little higher up the Kéwai, at the outlet of the Kétma, where
: there is a waterfall, 1 foot of coal is visible. No
Kétma Nadi, - ; ;
other outcrop occurs in this tributary, and for a
considerable distance to the north in the main river, and in its succes-
sive feeders, there are no signs of coal.
In the Chaurar, however, that joins the Kéwai on its right bank, and
on which stands Ningiiani, one of the principal
Cope eNs villages of the district, we again meet with a
fine seam of coal, as well as others of less value. The lowest in the
series is about 2’ 0” thick, and lies south of Urtan. Then above it is
the largest seam in the section ; it is exposed in the southern branch of
Chapéui Nala: seam the river, flowing from Chapani, under an over-
Cyt, hanging mass of sandstone. The measurement is
6’ 7”, but there is more of it under water. The coal seemed to me very
good, but, though I broke off a piece for analysis, it does not appear to
have reached the laboratory.
Proceeding to the main or northern channel, which is named Sin-
ghara, there are two other seams of coal, the
Singhéra Nala seams. 1 ver of which is not measurable. The upper one
is 2’ 3”, and, unlike most beds of coal, is not accompanied by any under-
clay. Above this there is nothing of further interest, but there isa very
fine extent of deep clear water, invitingly adapted for a mid-day swim.

of coal, we next have the Kanai, and its minor

but for those who in future years may have the curiosity to examine
them, I give a list of the village lands within whose limits they lie—

At Bichia the union of the Barnai and the Kéwai takes place, and
then the latter river forms, for about 7 miles, the boundary between the
Koréa and the Rewah States. West of Kérabahdra it is confined to
Koréa, and takes it rise between the upland peaks of Khéro and Dha-
marpinga. In this remaining part of the field, watered by the Kéwai
and its streams, there are not many seams of noteworthy size, but, as
usual, there are several of small dimensions, at Charwahi, Mouhari, Dagla,
Roji, Kérébéhéra, Chaton, Kaparia, and Pakriha. The principal expo-

p . sure of coal is in a branch of the Jhiria, north

Hestho River.—The next convenient division of the field is denoted
by the important drainage system of the Hestho. And justas the Sdn
is the paramount river in the Rewah State, so is the Hestho in the Koréa
State. A few minor tributaries of the Hestho on its right bank just reaeh
into Rewah territory, but with these exceptions the Hestho, at all events
in its upper course, is truly a Koréan river. It takes its rise in the heights

( 196 )

SOHAGPUR COAL-FIELD. 61

north of Sfinhat, the capital of Koréa, amongst the supra-Bardkar sand-
stones, and enters the field of the true coal-measures in the vicinity of
the town. Its course and that of many of its feeders lies in great part
in a hilly and impracticable country so far as communications are con-
cerned. In consequence of this physical drawback connected with the
coal-measures, the value of the different bands of coal is so reduced that 1
have curtailed my notices, and have passed by all but the larger and
more important seams with very brief allusions. All the details of
locality necessary to again find the outcrops that we met with are in the
Chapter of Appendices.
The Barakars are contracted in width in the Koréa State owing to
Productive measures denudation, and the chief feature in the distribu-
in south of field. tion of the coal is, that the productive measures
are confined to the lower horizon of the group, forming a narrow zone
along the southern border of the field.
Before describing the Koréan portion proper, there are two streams,
Kilharia and Jhiria the Kulharia and the Jhiria, tributaries of the
streams. Hestho, that rise in the Rewah State and which
I should first treat and dispose of. Being tributaries of the Hestho,
I left them for notice with the drainage system of that river, but the
accident of local position throws the coal-measures that are exposed
in them rather out of harmony with the restriction of the fiscal limits
of the Koréa State.
There are two seams of coal, of which the upper is exposed close to

south, but the rocks undulate, and the seam is again seen near Dimar-
kachar. The lower seam is visible at the confluence of the Kulharia and
the Jhiria at the foot of a waterfall. It is capped by greyish-white
felspathic sandstone, very soft at the surface with felspar decomposed ;
there is here and there a slight tendency to ferruginous segregation, but
not nearly to such an extent as in the regular Mahadévas, I make this

allusion as a warning, for, though the presence of iron is a very essential

This is much more favourable testimony to the excellence of the coal
than I anticipated ; the smallness of the ash is remarkable, and for the
future credit of the Sohagpir field, I hope this amount of 5°5 per cent.
will never be exceeded by this seam. With such fuel as this much
might be accomplished, but, unfortunately like most good things, it is
not to be easily obtained, being 86 miles further away from a line of rail-
Lae way than Umaria. The continuation of this

towards the Jhagrékhand seam is met with both to the north in the Jhagra-
bag or oa khand, and to the south in the Néori, 2 miles
south-east of Tanki village. My colleague, who traced it in the latter
direction, states that 6’ 4” are exposed and the rest hidden under water.
There is a thin parting of shale, and the quality of the coal is good.

Turning northward, the first tributary of the Hestho that concerns
. us is the Hasia. It is a rocky stream fed by
Hasia Nala. é : i
several branches from the direction of Bahia,

Misra, and Bahi. These all unite below the village of Bahi, and
thence the Hasia proper begins. Near the boundary of the Bardkars
with the Talchirs there is a commanding waterfall known as the Karam
Ghag, at the base of which some indifferent coal occurs. Quoting from
the manuscript report of Lala Hira Lal, “There are two seams north
of the very prominent dyke crossing the Hasia near the waterfall,
whose calculated thicknesses are 16 and 22 feet. They dip at high
angles.” Nothing is said as to their quality, but probably they will be
found of the same composition as those that have been analysed and tested.
Besides these, there are eighteen to twenty outcrops, but some of them

are repetitions of the same bed, and most of them are under the yard
limit. Only two are over it, bearing roughly east of Bahi, and measur-
ing 5’ 0” and 3’ 10” respectively. In the Kara-
Karakachdr Nala. . ; Sena :
kachar, which is the stream adjoining the Hasia,

there are only two full-sized seams amongst the many outcrops which
are visible. The lowest in the series measures 4’ 8’, A sample of it

was analysed, but the amount of ash was very high.

There are two other, but smaller seams.

Next comes the Dhinéti, into which several little streams fall,

ee: but I met with only three unimportant outcrops
between Ghitra and Bahia. There are some

fine waterfalls in its course, and the tongue of land enclosed by it and

the Hestho near their junction, is one of the favorite “ drives” of the Raja

of Koréa, Paran Sing, who is an enthusiastic sportsman.

After the Dhanéti comes the Hestho itself. Its scenery is repeatedly
ete, ates diversified by some PO NS ae

which is the one at Kirwaéhi forming the frontis-
piece. This is unquestionably the most striking and charming of all the
falls in this amply watered country. There is a broad sweep of rock
over which the greater portion of the stream precipitates itself in one
Srey. sheer drop, and then flows on through a long

winding gorge below, blocked with enormous
masses of debris, from amongst which and on which a rich vegetation
springs. It was a refreshing sight in the warm days of the summer
months, and I felt that I had parted with one of the sweets of life when
my duty obliged me to leave it behind.

Strange to say, there are no seams of noteworthy size or quality,
except one, in the whole length of the Hestho from where it enters
the area of the Bardékars near Sinhat to the point whence it leaves them

at Lai. It occurs at the end of the gorge below

In the face of the waterfall there are four carbonaceous bands, but it
is only the third in descending order that has true coal in it. Its thick-
ness is 3’ 6.”

Near the villages of Balsing and Basér there are indications of coal,
but from those localities eastward to within a mile
of the Jhilmili border, there is, practically speak-
ing, no coal with the exception of the belt of productive measures to the
south. Signs of carbonaceous deposits are not altogether wanting, but
they either rank clearly below the dignity of coal, or they are too thin,
or too indistinctly exposed to be classed definitely as worth consideration.

In this category are included the outcrops near

Balsing and Basér coal.

Outcrops, various, ns a ;: F x3
Kisaha, Amhdr, Stnhat, Orgai, Tunjara, Pathar-

gua, Bhoswai, and Latma.

Of the productive band to the south, the remarks which have already
been made of the area west of the Hestho give the reading. There are,
amongst many smaller seams, two of sufficient size to be workable under
the present ordinary conditions of Indian mining. To obtain a standard
section my colleague and myself ascended most of the streams, large
and little, which, curiously enough, have their watershed nearly coincid-
ent with the upper limit of the productive measures, but there was in
each instance too much incompleteness in the sequence of the rocks to
secure this result. We saw, however, outcrops after outcrops, which of
course were only the repeated symptoms of the same seams. The rivers
we examined specially were those of the villages of Lai, Harra, Kachar,
Nagar, Labji, Sardih, and Chircha.

Beyond Chircha is the border land of Jhilmili, the boundary between
which and Koréa passes by Roudserai and Tanjara, To the north-
PUM eo north-west of Roudserai, which is situated on the
new district road joining the capitals of the two

States, a good seam of coal occurs, but I could not see its entire thickness.

and south-west and separating the field into two narrow strips. Coal occurs
at several localities, but its value is reduced, as in Koréa, by the im-
practicable nature of the country.

In the northern strip of the field, the main stream is the Géknai,

crops of coal and carbonaceous shale. The prin-
cipal ones are exposed near the deserted village of Jumri.

occurs at the base of a waterfall, is not less than 6 feet. Angle of dip

This concludes the references to the distribution of the coal-measures
in this extensive field. The number of distinct seams is small, and for
such an area there is not an abundance of coal. The lateral extension,

Rafshiata gt nqientats however, is so great that the problem of how many
not made, million tons of coal are there, and for how many
years at a given rate of consumption will the coal last, may be left for

solution to the coming geologists of the twentieth century.

SECTION XI.—THE KURASIA COAL-FIELD.

This title, derived from the name of the only inhabited village within
the limit of the coal measures that it applies to, defines an independent
tract of Barakars lying south of the main area, and east of the Hestho
river in the Koréa State.

The superficial area is 48 square miles, and it embraces some very
wild country densely packed with bamboo jungle,
to which ferine elephants are wont to resort both
for food and shelter.

Owing to the difficulty of obtaining supplies for our camp, my col-

Survey of field incom. He) survey of the field therefore has not been a
plete. complete one, but the boundaries are sufliciently
defined to allow of their being published until such time as more finished
details are required.

These traverses proved the existence of coal, and the occurrence of the
ordinary rocks that accompany it elsewhere. On one of the higher hills
south of Kirdsia, there is a capping of supra-Barakar sandstone ; and
possibly on the Bartunga and Anjan hills there may be similar de-
posits. They were not visited, however, and I make the suggestion
merely on account of the heights marked on the map.

Seven outcrops of coal were met with, of which the three most important
are in the vicinity of the village of Kurdsia. The
finest seam, with a total measurement of 13’ 6,”
was discovered by Ladla Hira Lal at the head of one of the feeders of the
Kiudra, and the result of the analysis of a sample

it ought not to be overlooked.

about half way between Kdrdsia and the site of
the deserted village of Dabchdla. It is 8’ 0” thick,
and the coal is fairly good.

The remaining seams are inferior to these, and their positions only

SECTION XI.—THE KOREAGARH COAL-FIELD.

This independent area of Bardkars is a small basin, of which merely
the outline has been traced. It lies south-east of the Kir4sia field, and
nig covers about 6 square miles. The name given
to it was suggested by my colleague, from the

hill of Koréagarh, which is the highest point in it.
With respect to coal, only a hurried examination was made. No
seams of any value were noticed ; but this does not in the least imply
that they do not occur; and it is highly probable that with closer
search they will be proved. In his manuscript report Lala Hira Lal says :

for the scantiness of the details in connection with this field is, that two

SECTION XIII.—THE JHILMILI COAL-FIELD.

Under the above name, Mr. V. Ball, formerly of our Survey, desig-
nated a semi-detached portion of the main area

State; and as I am almost entirely indebted to the notes that he has
left behind him for the matter here published, I have retained both the
title and the limits that he selected."
So far as is at present known, the coal-measures occupy a lenticular-
; shaped area of about 41 square miles, with its
om ae ae long axis running S, W.—N. E. They are stated
to be faulted on the north, and thus brought into contact with an
alternate succession of Talchir and metamorphic rocks. To the south
they are for the most part but little disturbed.
The evidence of the main fault is very clear in a small stream near
the village of Tarka, the Barakar sandstones hav-

ing been lowered along a line of fracture to the
level of the more ancient rocks. In the M4nikmara stream, the faulted
character of the northern boundary is still more clearly exposed. Mr.
Ball states : “ North of the line of fracture, there are Talchir shales and
flags which are horizontal or slightly rolling towards the north. At the
fracture the edges of these beds are crushed and dragged down, and the
Bardkar sandstones close by are tilted to angles of from 40° to 50° to 8,
and S. E., their edges being in direct apposition to those of the Talchirs.
Associated with these sandstones, there are two small and much-crushed
seams of coal, measuring respectively 1’ and 2’ 0’. A more beautiful
and clearly-exposed example of the mechanical effects resulting from a
fault is not often met with.”
Of seams of coal, there are none exposed in the River Rér, on the
left bank of which the town of Jhilmili is built, and there are no
outcrops in the Pasla stream. In the Manikmara, ~

near thef ault, Mr. Ball found others, one of which was of excellent
quality. He describes the river section as follows: “A couple of
reaches above the northern boundary there is a step of sandstone, over
which the water falls from a height of about 30 feet into a deep hollow.
Passing this, another coal seam is reached, on the western bank of
Coal seam, 3’ 6” ex- the river; it exhibits an extraordinary amount of
Dee local disturbance, dipping at angles of 45°—50° N.
This high inclination is, however, soon lost, and not far off, on the eastern
bank, it is nearly horizontal like the accompanying sandstones. The
base of the seam is hidden. In the exposed portion there is about
3’ 6” of poor stony coal.
“ A short distance further up stream, just inside the mouth of a small
tributary, there is a seam of excellent coal, the top of which only is
Coal seam good. Only ¢Xposed, measuring 1’ 4”. The analysis made of
oe this coal by Mr. Tween freely justifies the good
opinion formed of it in the field :—

It is, moreover, a good caking coal. Its practical usefulness as a source
of fuel depends upon the total thickness of the seam. The amount and

direction of the dip is uncertain ; but the former is inconsiderable.
“Following the river up to the entrance of the valley north of the
Kaltanghat hill, the rise is so steep and constant that progression
entails a great amount of physical exertion. The stream falls over a
succession of steps formed of massive beds of sandstone, and three

coal seams are seen, bearing N. and N. E. from

All these seams are nearly horizontal, and accordingly so far favourable

two coal seams are imperfectly exposed. They are

probably identical with two of the seams described
above, as occurring in the Ménikmara section.”

There are no other remarks about coal exposures, but Mr. Ball men-

Coal fragments in tions that fragments of coal are abundant in the
Bebri Nadi. bed of the Gébri near Nouapara, and far south-
ward in the Talchir area.

The notice of the coal-measures of this field is confessedly imper-
fect, and Mr. Ball has been careful to say in his report that his examin-
ation was very hurriedly carried through, with a view merely to obtaining
a rough idea of the rocks to guide future more detailed work.

SECTION XIV.—SUPRA-BARAKARS.
Above the undoubted coal-measures are a succession of rocks extend-

of supra-Barékars, ships are as yet too uncertain for me to say with
confidence to what group or groups they should be assigned ; in order
to defer the solution of their classification to a more convenient season,
they are provisionally termed supra-Barakars.1

Their most prominent feature is the occurrence of ferruginous and

grees of induration and various ferric tints. There
are all gradations of texture, but coarse-grained sandstones predominate.
Pebble beds and likewise conglomerates occur. Shales—red, pink, laven-
der, and mottled (red, purple, and yellow) —are moderately frequent in the
lower portion of the group, and, being usually brightly coloured, readily
catch the eye. Clays occur occasionally.

As seen in the Jéhilla valley, where the best section in the whole of
the South Rewah area is to be met with, the sand-
stones are massively bedded, often false-bedded,
generally coarse-grained, and friable when not indurated by iron ; rusty

brown, salmon, and various shades of grey and yellow are the most com-
mon colours ; scattered pebbles and strings of pebbles are frequent; ferru-
ginous matter, either in bands, in strings, or in plates, or as a general
indurating agent, is freely distributed ; mica is not nearly so universal a
mineral component as it is in the Barakar group.

A very marked feature in many of the sandstones is their weathered

their surfaces are traversed by chisel-edged ribs
running usually in various directions, but occasionally presenting the

In some respects, that is, in reference to their petrological and litholo-
gical features, they might at once be placed partly with the Panchét group,
and partly with the Mahadéva group as understood in the Bengal

Conflict of palwontolo- CO0al-fields; but the palzontological evidence is
gical evidence. conflicting, for such fossils as have been found in
them indicate a somewhat lower horizon than that of the Mahaédéva.
Perhaps the Kamthi group, as defined in the Wardha valley coal-field,
would more fittingly embrace the various characters that appertain to these
supra-Bardkar beds, there being in that area a like assortment of clays,
varied sandstones, pebble beds, and abundant ferruginous matter. From
my published notes in the Records of the Survey it may be gathered
how strongly I was of opinion that in the valley of the Johilla the strata
immediately above the unquestionable coal-measures were Mahédévas.
On re-consideration, however, I think the suggestion of Dr. Feistmantel in
the Palwontologia Indica embodies a more reasonable view of the situa-
tion, and that some portion of the area mapped as supra-Barakars should
form an intermediate zone between the Mahadévds and the coal-measures,

Taking the section of the Johilla river in ascending geological order
from the Barakar boundary, there is a small island
at the mouth of the Bichna Nala, and in some pur-
plish, fine-grained argillaceous sandstone that forms a thin bed amongst
more massive sandstones that I had judged to be Mahadévas, I found

nous sandstones, which strengthened my belief that I was dealing with
a group high in the Gondwana series ; and it was, I confess, disconcert-
ing when the palwontological evidence was so much at variance with my
first conclusions. On the same line of strike are the rocks of Dhaurai,
Uchéhra, Karkati, Kurabar, and the Murcha Pass lying, broadly speaking,
to the north of the village of Pali composed of coarse pebbly sandstones,
yellowish, grey, massively bedded, and frequently with oblique lamina-
tion. At intervals, purplish fine-grained argillaceous sandstones and
brick-red clays, and fine-grained purple sandstones frequently so ferrugi-
nous as to become iron ore! beds. All these appeared to me to assimilate in
character with the Mahadéva group, but here also the paleontological facts
were, that at Karkati, in very ferruginous red-brown slightly sandy shale,
there were specimens of Hguzsetaceous stems, Schizoneura ? Sphenopteris
polymorpha, Glossopteris communis, Glossopteris cordata,and seeds. From
Kirabar, Vertebrarta indica, Schizoneura, Sphenopteris polymorpha, Glossop-
teris communis, Glossopteris damudica ; and from the Mircha Pass in very
ferruginous micaceous sandy shale, near Ganjra, Glossopteris communis.

have fossils distinctly newer than those of the Johilla and in the vicinity
of Pali, but they are associated with rocks whose features are quite iden-
tical with those of the latter localities, and we shall have to determine at
some future time what value this circumstance bears.

white sandstones. The rocks here will probably be assigned to either the
Panchéts or Kaémthis, as there are red lumpy shales, and white and pink
argillaceous sandstones, such as are frequently met with in the latter
group.

Over the remaining area embraced by the map in the eastern part of
the Rewah State, and in the Ching Bhakdr and Koréa States, I cer-
tainly think the supra-Bardkars are Méhadévds. It remains to be seen
whether paleontological evidence confirms this opinion, or whether the
value of our Gondwana fossil forms will have to be freshly appraised.

SECTION XV.—LAMSTA.

Of this group I have only to mention that it is utterly unconform-
able to all the series of rocks included under the heading of supra-
Bardkars, and that the distinctive rock in it is limestone. Sandstones
and clays occur; the former usually fine-grained, soft in texture, and
often greenish-grey and purple tinted; the latter are of various colours,
but more frequently deep iron-red and greenish.

The Laméta group is otherwise known as the Infra-trappeans, being
very extensively found underlying the Deccan trap, and closely related
to it and to the like deposits occurring between the trap flows, known
as Inter-trappeans. Both are fresh-water deposits, of upper cretaceous
or lowest eocene age. They have thus been compared to the similarly
placed Laramie group of North America (Records, G. S. I., xvii, p. 87).

SECTION XVI.—TRAP.

A large part of the trap that has been mapped in South Rewah is
elearly a continuation of the great Deccan (Dakhan) trap formation,
and it is found capping an extensive elevated area in the drainage basin
of the Jéhilla, and various portions of the Séhagptr and Koréa districts
to the eastward.

Within the coal-field there are well-defined sheets and dykes, and
the question which arises is, whether these are of different age to the
covering trap-flows. I can adduce no evidence that they are distinct,
and I have coloured them as belonging to the same formation.

( 210 )

ECONOMICS: COAL. 75

There are some instances of partial horizontal intrusion, and one
clear case is seen in the left bank of the Joéhilla river about a mile
north of Chichéra. At Harha on the Son there is another example, and
here the upper sandstone with which it is in contact is hardened, thus
showing that it is not a contemporaneous lava flow.

As a rule very little contact action appears to have taken place along
lines of intrusion: two instances may be mentioned, one between Mahrdi
and K4annabahara west of the town of Séh4gptr, and another near the
junction of the Rajehata and the Kantk, in which the varying steps
of alteration effected by trap are most clearly exhibited.

The first one was pointed out by Lala Hira Lal, where sandstone
has been changed not only into quartzite, but also into a highly erystal-
line rock resembling gneiss and granite. The belt of metamorphic
action is about 30 yards wide, and the trap is seen intruded in greater
or less quantities.

In the Rajghata noticed by myself, I was at first of opinion that
Thad met with an inlier of metamorphic rocks, but on closer investi-
gation it was apparent that the case was similar to that near Kdénnaba-
hara, and I was able to select specimens illustrating the various stages
of alteration from sedimentary sandstone to a rock which was quite
undistinguishable in the hand from ordinary granite.

These instances of metamorphism are interesting owing to their
rarity, as in no other coal-field have I observed the same phenomena,

I have previously drawn attention to the fact of there being in the
Appendix a list of all the places at which outcrops of coal have been
found in the various fields described in this memoir. I propose reducing

my remarks under the present section of Economie Geology to the facts
in connection with the coal of the Umaria field, its greater geographical
importance, and the more complete determination of its value as com-
pared with those of the other coal-measure areas, having made it the real
gauge of their present worth.

As at present proved in No. 7a bore-hole, there is a maximum thick-

Thickness of coal in Mess of 24 feet of coal at a depth of 184 feet from
No. 7a bore ole, the surface. This is accumulated in two seams
measuring respectively 13 and 11 feet, and separated by 25 feet of car-
bonaceous sandstone. The outcrop of the lower of these is visible in the
Umrar river near Kalésar. It is traceable thence westward through
ravines and gullies south of and near to No. 1 shaft. From that point,
there is no sign of coal in the direction of the Narsara Nala or elsewhere,
and it becomes a matter of supposition as to how the outcrop runs,
Probably the strike changes, and veering to the north-west and north
gradually becomes parallel with the Chatan range of hills. Speaking
generally, the dip of the measures within the exposed limits of the field

Toei is to the north-east at a low angle; but from the
evidence in No. 2 shaft there is the probability
of local variations, for the level course at that spot in the field is
north-east and south-west. Such variations, however, are always to
be expected, and do not affect the main dispositions for the working of a
colliery.

There is no evidence of the second seam at the surface, but I think
that the journals show it to be nearly co-extensive with the lower
seam. Many of the borings were not carried through the whole
thickness of the coal bands, but such as were, bear testimony to two
seams,—as, for example, those where the shafts are placed, and Nos. 7a
and 16.

In speaking of the thickness of the coal, then, we may reasonably
assume that after excluding a superficial breadth of 500 feet from the
outcrop of the lower seam, measured in the direction of the general dip,
there is quite 20 feet of it.

an area of 4 square miles at a depth of 500 feet
from the surface. I merely give this estimate to satisfy the desire for
figures which seems inseparable from the mention of a coal-field. The
statement that there are 55 millions of tons of coal within a given area
expresses the value of a restricted portion of the coal-measures.

There is every likelihood that coal occurs under the supra-Barékars in
the direction of Gangri, Maihmar, Kua, and Piparia, and that it extends
continuously to the exposed edges of the Korar field. Such a contin-
gency as this, of course, raises the total quantity of coal, and the union
of the Umaria and K rar fields through Chirwar, Mirgiri, and Barbaspiar,
and so on, increases the number of tons to a formidable amount,

Abundant opportunity has been afforded for judging both of the

Nature of seam and ature of the seams and the quality of the differ-
quality of coal. ent bands of coal that they contain. In reference
to the outcrop explorations, Mr. Forster says that the coal works easily,
and that the thin band of soft shale under the bottom of the seam will
facilitate pricking, and so reduce very materially the amount of waste.
The roof is an excellent one, and, except quite near the entrance to the
different inclines, not a single stick of timber has been required to sup-
port it. This is a most favourable feature in the estimation of a seam,
for when the roof is bad the expenditure under the heading of timber
forms a considerable item; and there is the constant dread of accidents
to life,

In No. 2 shaft the coal can easily be got in large blocks, and up
to the present time the roof has shown no signs of weakness.

The composition of the coal has been determined by several assays
made by M. M. Mallet and Fedden and Lala Hira Lal in the labora-

The main stay of the seam is the bottom portion, and there is no
Botton a pores on disputing its worth. Bearing in mind that the
Beata Good) eusarucaa specimens examined were from the outcrop, we
have in the analyses before us the worst aspect that the coal presents,
and as this is better than that of the average of the fuels from the Rani-
ganj field, we have at the outset a high standard of excellenee.

The coal has a dull look like that of the best Karharbari coal, and is
very compact.

It appears to be homogeneous, but when separated into its layers,
finely divided mother-of-coa] is visible on most of the faces. This is
a favourable feature and usually means that the coal will have consider-
able heating power. It ought to be a good steam coal, and it bears
transport well.

A strong point in its favour is the manner in which it withstands

Coal withstands Weathering. A stack was left exposed to the full

at the end of that time the coal showed no sign of deterioration.
Usually the laminated coals of Bengal and the Wardha valley split
into thin papery layers when left unprotected, and occasionally they
take fire, but in both these respects the Umaria coal has proved very
satisfactory.

No attempt has yet been made to produce coke in ovens, but my

The running power of the coal has been tested on several occasions
Running power of 02 the East Indian and Great Indian Peninsula
eral Railways, and with one of the trial trips on the
latter line I was personally concerned. Reports were drawn up by the
Locomotive Superintendent of the Great Indian Peninsula Railway and
by Mr. Thomas Forster, the Manager and Mining Engineer of the
Umaria Colliery, and I give extracts from them further on.

The coal was from the outcrop galleries, and no other care was taken
than to pick out the clinker band, There was no selection, and the
average of one consignment will be the average of another until the
character of the seam itself varies. After the necessary arrangements,
the local foreman of the line, Mr. Forster and myself left Jabalpir on
the 12th May 1884, with a baggage train of an average gross weight,
excluding the engine and tender, of 410 tons, and our run was to Sohaég-
pur, a distance of 122 miles. Mr. Forster, in addressing the Political
Agent of Rewah, stated :—

“‘T have the honour to submit a report of the
trial trip made on the night of the 12th instant.
« By the kindness of the Traffic Superintendent, Mr. Maurice, we

were given a full train-load of 32 vehicles, the biggest load run on the
portion of the line between Jabalpur and Gadawara. The locomotive
supplied by Mr. Watson of the Locomotive Department was all that
could be desired for trial of coal.

“We started from Jabalpar at 10-20 p.m., arriving at Sohdgpdr
about 9 A.M. on the morning of the 15th.

“T am exceedingly glad to say that the coal steamsadmirably. Even
when going up hill with the full load, steam was blowing off from the
safety valve. The fire was cleaned out twice on the journey, not that it
was really necessary, but it is better always to trim the fire in a journey
so as to prevent the fire-box getting chocked and so prevent the admis-
sion of air.

“ On arrival at Sohagpar we found that the Traffic Superintendent
had telegraphed permission to weigh the train.

( 216 )

ECONOMICS: COAL. 81

“The gross average weight amounted to 410 tons.

“ At starting we had 3 tons 16 ewts. and 19 lbs. of coal on the
tender, lighting up of engine included. The amount of coal left on
tender after completing the trip was 1 ton 9 ewts. 2 qrs. 2 lbs. The
consumption on the journey was therefore 2 tons 6 cwts, 1 qr. 21 lbs.

“The evaporation was 54 Ibs. to 1 Ib. of coal.”

“ Reducing these figures to the standard of pounds consumed per train
mile, we have 8,531 Ibs. —3,330 lbs. = 5,201 lbs., the actual amount

burnt.” Then ©2Ls. = 42°63 Ibs. per train mile.

“This compares favourably with Karharbdari coal, as a 500-ton train on
the East Indian Railway is run at the rate of 48 lbs. per train mile.
Then 500 tons : 48 lbs. :: 410 tons = 39°36 lbs. per train mile for same
weight of train.

‘«Tke average consumption per mile of the Mohpani coal! is 55 lbs.,
so that we ran 12°37 lbs. per mile less.

“T think this speaks well for the quality of the Umaria coal, and
places beyond doubt the assertion that it is an excellent country fuel.
During the trip I noted particularly that very few sparks were thrown
out, and that the coal is not more fuliginous than the general run of
country coal.”

I am of opinion that Mr. Forster has given more credit to the
Mohpani coal than it is entitled to, for, in the last annual report of the
Director of Railways, the all-round figures per train mile are 100.

clinker, but a large amount of ash; it throws very few sparks, and
makes little smoke. It should not be forgotten that the above report is
based upon a small consignment which we have received from the col-

that if coal such as has been sent to us can be guaranteed, we could have
nothing to complain of.”

although there is no gainsaying an assay, it is pleasant, when advocating
the claim of any given object, to find engineers and chemists in accord
with each other. And I think it reasonable to conclude that even in the
outcrop coal at present being worked in the Umaria field, we have a high-
class fuel.

In No, 2 shaft much better coal has been reached, the amount of

Excellent coalin No.g fixed carbon that it contains showing a marked

aD advance on that of the very best of the samples

from the outcrop workings. I again give the analysis :—

EXCLUSIVE OF WATER.

Volatile matter, Fixed carbon, Ash,

No. 2 shaft . . . ° 0 25°17 66:71 812

None of this coal has been tried for locomotive purposes, but it
should equal anything turned out either by the Karharbari or Raniganj
fields.

In view of attempts to utilise the magnificent resources of the Jabal-

Coal in reference to Pur district for the production of iron, the small
SUNBEDS AE amount of ash is a most promising feature, for
one of the greatest drawbacks in connection with the endeavours to make
pig-iron in the Wardha valley at Warora was the large quantity of
impurity in the form of ash that the fuel contained. It was quite 50 to
60 per cent. in excess of that in the Umaria pit coal.

ECONOMICS : IRON ORE. 83

After exactly three years of preliminary explorations,! the Umaria field
has passed from the control of the Rewah Adminis-

Transfer of control M
from Rewah to Govern- tration to that of the Government of India, who

pk oe have decided to work it during the minority of
the Mahdrajah and to pay a handsome royalty of eight annas a ton on
the raisings.

With unquestioned credit, and absolved from the necessity of large
profits, the Government of India can increase its area of distribution to
a much greater extent than the policy of any private company would
permit, and therefore with larger proportionate raisings, the arrangement
that has been entered into is the very best possible for the Rewah State.
A fixed annual rental could never have been calculated at the true rate
of production, whereas a royalty binds in equal degree the interests. of
the colliery and the lord of the soil.

Under the title of the Umaria Coal Estate, E have indicated the limits

Umaria Conl Estate Of the area over which it would be well to acquire
OEEINESe surface and mineral rights, so that future mining
operations may be carried on without the recurring necessity of taking
up fresh land and re-opening negotiations regarding its value.

The boundaries agreed upon have the advantage of being distinct
and simple; they are, the range of Chatan hills to the west, the Umrér
river to the north and east, and the line of railway to the south, and.

include a superficies of about 4 square miles.

SECTION XVIII.—IKON ORE..

I have no information to proffer regarding irom ores, but im so far as
the possibility of using Umaria coal to utilise the magnificent deposits
of iron in the Jabalpar district brings the coal-field into relation with
them, I would mention, for the information of those who may be interest-
ed in bringing smelting operations to a practical issue, that in the Re-
cords of the Survey, Vol. XVI, Part 2, Mr. F. R. Mallet has given
all the most important facts known regarding the iron ores, and subsi-
diary materials for the manufacture of iron in the north-eastern part of

1 The first boring was commenced 22nd January 1882, and the coal-field, comprised
within the boundary of the Umaria Coal Estate, was transferred 21st January 1885.

the Jabalpir district. In the early part of 1881 Mr. Trimnell was
successful in treating the iron ores in the neighbourhood of Mtrwé4ra,
but the fuel employed was charcoal. No attempt has been made to use
Umaria coal, but I have lately been informed that the Government
(Central Provinces) intend making a few trials with some best selected
pit coal as fuel. Instead of carrying out independent experiments, how-
ever, I think the better plan would be to forward ore and fuel to the
Bardakar iron-works where the whole process of manufacture has been

brought under practical control.

SECTION XIX.—LIMESTONE.

Limestone is found abundantly in the form of rock limestone, wherever
the Laméta group is developed.

The Bij4war formation also yields it; and within the Lora meta-
morphic inlier there are beds of crystalline limestone.

The Laméta limestone varies a great deal, and care must be exercised
in its selection if it be intended for use.

Kankar is freely distributed, but its occurrence in large nodules is
restricted to small areas. Tufa or travertine is also met with.

The following analyses show the average composition of the different

lime-bearing sources :—

ECONOMICS: BUILDING STONES, 85

SECTION XX.—CLAY.

There appears to be a great want of good clay for even ordinary bricks
in the Umaria coal-field, and in default of better material the arenaceous
alluvial clay along the banks of the Umrar river has to be used. A very
limited amount of clay is procurable in the tanks around Umaria,
but it will not hold out for long. Perhaps the scarcity of a suitable
substance for brick-making may force the use of stone, which in my
opinion would be an advantage, as ensuring more permanency in the
buildings that may have to be erected. The village potters of Umaria
and Kalésar, after specially treating the sandy clays, make excellent
porous drinking-vessels.

SECTION XXI.—BUILDING STONES.

Considering the large area of sandstones over which choice may be
made, it would not at first sight seem a difficult task to procure building
stone suitable for most purposes. From the statements, however, of the
various engineers who have been engaged upon the survey of the Bilds-
par-Etawah Railway, it appears that the scarcity of good stone is a very
serious embarrassment in their plans for heavy bridging.

The sandstones of the coal-measures are all soft when really quarried,
but they possess the advantage of hardening by exposure to the air.
Closed-grained sandstones occur in plenty throughout the Upper Bardkar
series, and I am of opinion that it merely requires search to obtain stone
of suitable strength. Probably the question of the lead (distance) has
more to do with the perplexity of supply than anything else.

Beyond the Umaria field, exeellent material is procurable between
Kirintal and Amha, and the rollers and grindstones in use at the Umaria
colliery are obtained from the quarries in the neighbourhood of those
villages. For less exact requirements than those of bridges and engine

foundations, the coal-measure standstones would fully answer.
